Petrossian Bar

Petrossian Bar

Petrossian Bar is Bellagio's lobby caviar-and-champagne lounge under the Chihuly ceiling — live piano in the evenings, real Ossetra service, the caviar-cone Bellagio Martini, and afternoon tea Fri-Sun. Open daily 10am-1am.

Is Petrossian Bar Worth It? Honest Review

Petrossian Bar is the Bellagio lobby's resident aristocrat — a caviar and champagne lounge parked beside the front desk, directly beneath Dale Chihuly's two thousand glass flowers, with live piano carrying the evenings. It has survived every renovation cycle intact and remains the resort's most civilized twenty minutes.

The caviar service is the genuine article — Imperial Ossetra, Royal Daurenki, and Baika tiers, with a trio flight pairing thirty grams against Veuve Clicquot pours or a vodka flight — and the kitchen has fun at the margins: caviar tacos, cones, even donuts. The Bellagio Martini arrives crowned with a tiny caviar cone; cocktails run $20-28. English afternoon tea holds its Friday-Sunday 1-4pm slot, a Vegas anachronism worth protecting.

Costs and context: caviar service climbs into the hundreds, the room is open to the lobby's full foot traffic — this is people-watching as amenity, not privacy — and Conservatory crowds wash through at bloom changes. The piano makes the room after dark. As a pre-fountain or post-show stop, it has no real competitor on the Strip's luxury end.

Insider tip Time it to the Conservatory: arrive as evening piano starts, order the Bellagio Martini (it lands with a mini caviar cone), and you've built the best pre-fountain hour on the Strip for the price of one drink. Book ahead only for tea and full caviar service.

Frequently asked questions

When is Petrossian open?

Daily from 10am to about 1am, with live piano in the evening hours and English afternoon tea Friday through Sunday, 1-4pm (reservations recommended for tea).

How expensive is it?

Cocktails run $20-28; caviar service is the real spend, running into the hundreds for the top tiers. The trio flight — three 30g pours with champagne or vodka pairings — is the structured way in.

What's the signature order?

The Bellagio Martini: Grey Goose, garnished with a miniature caviar cone. Around it, the kitchen plays with caviar tacos, cones, and donuts — luxe bites, not dinner.

Do I need a reservation?

The bar itself is walk-in; reserve (OpenTable) for afternoon tea and full caviar service. Peak lobby hours — check-in waves, Conservatory bloom openings — fill the seats fastest.

Is it quiet?

It's elegant but public — open to the full lobby thoroughfare, so foot traffic and luggage wheels are part of the soundtrack. The piano covers it after dark; expect ambiance, not privacy.
